That's called trading sometimes goes up sometimes down, cryptocurrency like Bitcoin is also experiencing the same thing.
* You remember in 2017 the time went up, and when the price of Bitcoin dropped to a drop of $ 3000, without stopping.
* You remember yesterday when mid-2019 when rising, who would have guessed.
In the world of investment, it is highly prioritized, patience, do not panic, for the future everything will improve, maybe this is an influence on the world which is currently struggling with the economy.
Just one correction, fall from 20k to 3k wasn`t a straight line. As I remember, checking charts from that period can confirm that. Everything else you stated is true, when people trade too much, price will fluctuate, when you add high rollers who trade with huge amounts, price will go down/up very fast.
People will panic no matter what we say. We already seen huge rise this year, but this little drop affected people to think about the worst case scenario, again. It`s like that since I`m here, price was 200 dollars, can you imagine that? With every drop, people wrote about some doom, the best thing to do is to not pay attention.
